scsi: ultrastor.c depends on ISA_DMA_API

Fix build when CONFIG_ISA_DMA_API is not enabled. Fixes these build
errors (on x86_64):

     if (config.dma_channel && request_dma(config.dma_channel,"Ultrastor")) {

../drivers/scsi/ultrastor.c:658:3: error: implicit declaration of function 'free_dma' [-Werror=implicit-function-declaration]
